Horace Trumbauer (December 28, 1868 – September 18, 1938) was a prominent American architect of the Gilded Age, known for designing residential manors for the wealthy. Later in his career he also designed hotels, office buildings, and much of the campus of Duke University. Trumbauer's massive palaces flattered the egos of his "robber baron" clients, but were dismissed by his professional peers. His work made him a wealthy man, but his buildings rarely received positive critical recognition. Today, however, he is hailed as one of America's premier architects, with his buildings drawing critical acclaim even to this day. Career Trumbauer was born in Philadelphia, the son of Josiah Blyler Trumbauer, a salesman, and Mary Malvina (Fable) Trumbauer. He completed a 6-year apprenticeship with G. W. and W. D. Hewitt, and opened his own architectural office at age 21. He did some work for developers Wendell and Smith, designing homes for middle-class planned communities, including the Overbrook Farms and Wayne Estate developments. Trumbauer's first major commission was Grey Towers Castle (1893), designed for the sugar magnate William Welsh Harrison. Its exterior was based on Alnwick Castle in Northumberland, England, although its interiors were French, ranging in style from Renaissance to Louis XV. Harrison introduced him to the streetcar tycoon and real-estate developer Peter A. B. Widener, whose 110-room Georgian-revival palace, Lynnewood Hall (1897–1900), launched Trumbauer's successful career. For the Wideners, the Elkins's, and their circle he designed mansions in Philadelphia, New York, and Newport, RI. Through these connections, and others, he designed office buildings, hospitals, and institutional buildings. Known for his academic facility designs, some of his most notable works include commissions for the University of Pennsylvania, Harvard University, Duke University, and others. Harvard University's principal library, the Harry Elkins Widener Memorial Library, was built with a gift from Eleanor Elkins Widener as a memorial to her son, Harry, Class of 1907, an enthusiastic young bibliophile who died on RMS Titanic. On April 25, 1903, Trumbauer married Sara Thomson Williams and became stepfather to her daughter, Agnes Helena Smith, from her previous marriage to iron dealer C. Comly Smith. Architectural Record published a survey of his work in 1904, less than a decade after his first major commission. In 1906, Trumbauer hired Julian Abele, the first African-American graduate of the University of Pennsylvania Architecture Department, promoting him to chief designer in 1909. Many of Trumbauer's later buildings are largely attributed to
